After the interview, I was added to WeChat by personnel.

1, the other party did add you for work reasons, and he asked you to add him, so you can boldly ask how the interview went, whether there was any result, or express your thoughts on the new job.

2. If the other person has any thoughts about you personally, add your WeChat under the banner of recruitment and ignore you to keep your appetite. It is also possible. However, you can ask casually on the grounds of work.

To sum up, no matter what his purpose is, he can ask questions directly on WeChat. If you ask questions about work, don't ask "Do you like me?" There will be endless troubles.
